Episode notes

The accuracy to range an object in the daytime is the same as the accuracy to range the object in pitch darkness if you are using our head, our algorithms. In say three years time, we should be able to have various kind of vendors who are bringing together thermal cameras, spectral filters and algorithms. And it's just kind of a packaged camera that you can use every single night.

In this episode:

00:46 How to see in the dark like it’s daytime

There are many methods for better night-vision, but often these rely on enhancing light, which may not be present, or using devices which can interfere with one another. One alternative solution is to use heat, but such infrared sensors struggle to distinguish between different objects. To overcome this, researchers have now combined such sensors with machine learning algorithms to make a system that grants day-like night-vision. They hope it will be useful in technologies such as self-driving cars.
